Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 311 



Holotype (No. 377) male, in collection of the California 

 Academy of Sciences. 



Allotype, female, in collection of Mr. Giffard. 

 Paratypes in both collections and in that of the author. 



339. Naethus fenestratus Melich. Los Altos, July 26, 

 1916; Alt. Tamalpais, August 16, 1916; Niles Canyon, July 

 14, 1916; near Lakeport, 2500 feet, August 2, 1916. 



340. Daneptcryx nianca Uhl. San Francisco, June, 1916, 

 Redwood Canyon, July 2, 1916, August 6, 1916; Dublin 

 Canyon, May 6, 1917. Melichar has described one species 

 in this genus (lunda), and Kirkaldy two {harbarco and arte- 

 luisice), but I am unable to find any characters by which to 

 distinguish them. Mr. Giffard has very kindly brought me 

 a female specimen of harharce, labeled as such in Kirkaldy's 

 own handwriting, and there is only the paler brown color to 

 distinguish it. Kirkaldy says "front wider", but the wider 

 front is characteristic of the female nianca; he states that 

 the base of the front is truncated but that character depends 

 upon the development of the individual and it is not truncate 

 in Kirkaldy's specimen before me ; the longer pronotum is 

 also a character of the female sex in this genus. The only 

 useful characters left for harharce are its paler color and 

 larger size and I am not sure but both may depend upon 

 maturity. Both forms are found together upon the same 

 bush throughout California as is also a blackish form with 

 pale elytra which seems to be conspecific. This is one of our 

 most abundant insects, being found everywhere upon sage- 

 brush. I have retained the four names in my catalogue until 

 someone has the time to make a careful microscopical study 

 of the male genitalia and other characters. 



341. Pissonotus delicatus melanurus, new variety 



Like the typical form in every respect except that the fulv- 

 ous portions are deepened to piceous in the female or black 

 in the male. The genital characters are obscure but do not 

 seem to differ in any respect from those of the species. This 

 is a pretty form of a piceous or deep black color with the 

 head, pronotum and broad apical margin of the elytra white; 

 the base of the tergum beneath the white margin of the elytra
